On a clear blue sky day one airplane left on a westbound trip, while another departed on a southbound adventure, both bound to be on time for an unknown converging mid-air path. If the data of these two flights had been communicated, applied corrective actions would have separated their paths.
|A once perfect project may over time reveal its flaws.|
People are the strength of all safety processes with a unique ability above and beyond any automation in resilience, and the understanding of communicated data. Collected data of special variations are accumulate knowledge. This knowledge makes you wiser, not just older. How insignificant the data might seem at the time, it's an asset to improve safety.
|Special variations may be obscured by the view.|
Communication is a key factor to manage safety. Tools and technology for effective communication to avoid time converging events may not be available at all locations, or in all types of airspace. The time to "time of no return" becomes relatively short when pilots first have to establish visual contact.
Special variation management is to discover the unpredictable sequence at which these variations are revealed.
